国旗下的讲话：第十八届“世界水日”珍爱每一滴水
老师们，同学们，今天——XX年3月22日是第十八届“世界水日”，3月22-28日是第二十三届“中国水周”。联合国确定的XX年“世界水日”主题是“关注水质、抓住机遇、应对挑战”，我国纪念XX年“世界水日”和开展“中国水周”活动的宣传主题为“严格水资源管理，保障可持续发展”。关注新闻的老师和同学都知道，我国的云南省正在遭受60年不遇的大旱，几个月没下雨。河塘干涸，水井干枯，600余万人饮水困难，3000万亩农田受灾。更可怕的是，据气象专家预测，云南的旱情有可能持续到5月份雨季到来之前。我们的家乡天津也是一个缺水的城市。天津自身没有水源，降水量也小，缺乏贮存水的条件，目前，天津的城市用水主要依赖滦河水。1983年竣工的引滦入津工程全长234千米，是当时中国最长的引水工程，平均每年向天津市输送 亿立方米的淡水。但是，引滦工程并没有彻底解决天津的水危机。尤其是最近几年，我国北方地区连年干旱，水质污染，水资源的可利用量日趋紧张，而用水浪费则进一步加剧了水资源的短缺。
国旗下的讲话 让安全与我们同行,让生命放出异彩
第一篇：尊敬的各位老师,亲爱的同学们:大家上午好!今天我发言的题目是:《让安全与我们同行,让生命放出异彩》又是一个草长莺飞,鸟语花香,万物复苏,春意盎然的季节;又到了我们学生校内游戏,郊外踏青,城里观光,远方旅游的好时节.那我不禁想到:在这一系列愉快的活动中,你想到安全问题了吗你的安全意识增强了吗面对活动中的一切不安全问题,你准备好了吗……同学们,每年三月的最后一个星期一被定为全国中小学生"安全教育日",今天是第十一个"安全教育日",今年的主题是"珍爱生命,安全第一".安全工作历来是学校工作的一个重要组成部分.据报道,我国每年约有1.6万名中小学生非正常死亡,中小学生因安全事故,食物中毒,溺水,自杀等死亡的,平均每天有40多人,就是说每天有一个班的学生在"消失".安全事故已经成为14岁以下少年儿童的第一死因.可见,珍爱生命,防止校园伤害,创建"平安校园"是多么重要啊!
关于倡导低碳生活，打造绿色校园的国旗下讲话
倡导低碳生活，打造绿色校园xxx班 xxx亲爱的老师，同学们：早上好!我是xxx班的xxx。今天，我国旗下讲话的题目是《倡导低碳生活，打造绿色校园》。现在我国正在积极倡导“低碳生活”。所谓“低碳生活”，就是指生活中所耗用的能量要尽力减少，从而减低二氧化碳的排放量。我们应该积极提倡并去实践低碳生活，要注意4个节约：节电、节水、节油、节气，从这些点滴做起。也许有同学会问，节能减排，应该是政府和企业关注的事，似乎和我们学生无关。那你就错了，社会大家庭中的每一个人，都与这件事密切相关！大家知道吗？如果人人养成随手关灯的好习惯，那么全国每年可节电约20亿千瓦时，减排二氧化碳188万吨。如果每年全国有10%的纸巾使用改为手帕代替，那就可减少纸张消耗约万吨，节能2万吨的标准煤。现实生活中，我们每节约一滴水，一度电，一张纸，一粒粮食，都是对环保的贡献；生活垃圾的合理处理，废旧电池的合理回收，对校园及其他公共绿地的爱护，对身边有损环保现象的劝阻……所有这些，都是我们应尽的社会责任。

第十八届“世界水日”国旗下的讲话：珍爱每一滴水老师们，同学们，今天——XX年3月22日是第十八届“世界水日”，3月22－28日是第二十三届“中国水周”。联合国确定的XX年“世界水日”主题是“关注水质、抓住机遇、应对挑战”，我国纪念XX年“世界水日”和开展“中国水周”活动的宣传主题为“严格水资源管理，保障可持续发展”。关注新闻的老师和同学都知道，我国的云南省正在遭受60年不遇的大旱，几个月没下雨。河塘干涸，水井干枯，600余万人饮水困难，3000万亩农田受灾。更可怕的是，据气象专家预测，云南的旱情有可能持续到5月份雨季到来之前。我们的家乡天津也是一个缺水的城市。天津自身没有水源，降水量也小，缺乏贮存水的条件，目前，天津的城市用水主要依赖滦河水。1983年竣工的引滦入津工程全长234千米，是当时中国最长的引水工程，平均每年向天津市输送亿立方米的淡水。但是，引滦工程并没有彻底解决天津的水危机。尤其是最近几年，我国北方地区连年干旱，水质污染，水资源的可利用量日趋紧张，而用水浪费则进一步加剧了水资源的短缺。
读书节国旗下讲话：让读书成为最美好的生命举止
尊敬的老师、同学们：早上好！今天，我发言的题目是《让读书成为最美好的生命举止》春暖花开的四月，我们将迎来xx三中的第六届读书文化节，每年的这个季节，我们的校园繁花盛开书香飘逸，鲜花装点校道，书香涵养性灵。让我们一同走进翰墨书香的世界，不为分数，不为排名，只因为，阅读，确确实实是一项最美好的生命举止。古人说，书中自有黄金屋，书中自有颜如玉。不可否认，书籍能让我们增长知识和才干，能给我们的未来打下坚实的基础，能给我们带来许许多多可以触摸、可以预期的利益。然而，在这个花香满园的四月，我更愿意提倡同学们去读那种能让人心灵沉静，能促人思考，能给人智慧的书。宋代黄山谷说：一日不读书,尘生其中；两日不读书,言语乏味；三日不读书,面目可憎。就我的理解，这里所说的如果不读就会让人面目可憎的书，不会是那些能产生立竿见影效果的工具书或各类方法大全，也不会是我们许多同学曾经心爱的《知音漫客》或者各类练习册、试题集，而是像曹雪芹的《红楼梦》、罗曼罗兰的《名人传》、培根的《培根论说文集》、摩罗的《悲悯情怀》这样的书

海关法研究会会长在海关法论坛闭幕式上的总结发言
比如刚才我们讨论的很多海关法的一些争议和问题，例如研究走私罪的罪和非罪、此罪和彼罪、关于犯罪形态的问题。刑法学是有范畴的，就是犯罪的构成要件和犯罪构成要件的特殊形态。用这个去研究它，它就会得出一个相对确定的结论。民法学也是一样。但是在海关法里我们看不到有一个关于海关法的构成要件的学说。我们在海关法的讨论当中，大家都会从自我的实践中主观地提出一些建议。但是由于我们没有这种范畴和知识体系，没有用这种要件的方法或者原理的方法来指导我们，所以我们得出来的结论都是不确定的，这样得出的东西就会导致“公说公有理婆说婆有理”，他就不是一个科学的方法。这个层面是我们很欠缺的。我一直有一个愿望，要写一个没有一个海关法条文的海关法著作。如果能够写出这种著作，那就真的代表我们变得科学了，否则我们现在的海关法研究就没有突破科学这张纸，它就依然是很幼稚的。
消防大队夏训总结暨练动员部署会议上的讲话
三、精准施策，科学部署夏训工作要想解决好执勤训练工作中存在的问题，我们就必须把“能打仗、打胜仗”的练兵鲜明导向立起来，建立长效机制，坚持治标兼治本，做到“统筹谋划、科学部署，科学推进、有条不紊，全力保障、全面提升”。1、以目标定向。建立夏训工作目标清单，清晰的时间表、制定保障机制三项工作。这三项工作要明确工作做什么、怎么做、如何保障，达到什么成效。2、建章立制。坚决纠正坐而论道，完善考评机制，解决干与不干、干多干少、干好干坏一个样的问题，使能带头带好头的干部受到褒奖和鼓励，使不干事、庸懒散、无责任心的干部受到鞭策和惩戒。3、科学组训。优化练兵方法、细化练兵方案、强化练兵研讨，明确“练什么、怎么练”的问题，助力履职尽责。4、多重激励。要从政治上、精神上、经济上建立健全奖惩激励机制，提升练兵热情，着力营造“你追我赶”的练兵氛围。5、服务保障。要着力解决保障明显不足的问题。
人教A版高中数学必修一单调性与最大（小）值教学设计（1）
《函数的单调性与最大（小）值}》系人教A版高中数学必修第一册第三章第二节的内容,本节包括函数的单调性的定义与判断及其证明、函数最大（小）值的求法。在初中学习函数时,借助图像的直观性研究了一些函数的增减性,这节内容是初中有关内容的深化、延伸和提高函数的单调性是函数众多性质中的重要性质之一,函数的单调性一节中的知识是前一节内容函数的概念和图像知识的延续,它和后面的函数奇偶性,合称为函数的简单性质,是今后研究指数函数、对数函数、幂函数及其他函数单调性的理论基础;在解决函数值域、定义域、不等式、比较两数大小等具体问需用到函数的单调性;同时在这一节中利用函数图象来研究函数性质的救开结合思想将贯穿于我们整个高中数学教学。
人教A版高中数学必修一单调性与最大（小）值教学设计（2）
《函数的单调性与最大（小）值》是高中数学新教材第一册第三章第2节的内容。在此之前，学生已学习了函数的概念、定义域、值域及表示法，这为过渡到本节的学习起着铺垫作用。学生在初中已经学习了一次函数、二次函数、反比例函数的图象，在此基础上学生对增减性有一个初步的感性认识，所以本节课是学生数学思想的一次重要提高。函数单调性是函数概念的延续和拓展，又是后续研究指数函数、对数函数等内容的基础，对进一步研究闭区间上的连续函数最大值和最小值的求法和实际应用，对解决各种数学问题有着广泛作用。课程目标1、理解增函数、减函数 的概念及函数单调性的定义；2、会根据单调定义证明函数单调性；3、理解函数的最大（小）值及其几何意义；4、学会运用函数图象理解和研究函数的性质.数学学科素养

【设计意图】以“新科技是一把双刃剑”为主题开展讨论活动。这个话题比较大，所以给了一定的限制，首先需要以智能家居为例来阐述科技发展对未来生活产生的影响，然后列举其优点和缺点，最后就以上现象发表自己的观点。这个活动是对整个文本的创意性总结与意义的升华，留给学生一定的想象空间，学生借此机会可以运用文本内容和语言表达自己对科技发展的看法和态度。Assignments:1. Finish Exercise 4 on Page 15 of the textbook.A smart home is one that integrated computers into the structure of the building itself. In this way, many of the things that we now do ourselves become automatic. For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on and off, and so that your home would be more energy-efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.

(2)方法一:第一次取到一件不合格品,还剩下99件产品,其中有4件不合格品,95件合格品,于是第二次又取到不合格品的概率为4/99,由于这是一个条件概率,所以P(B|A)=4/99.方法二:根据条件概率的定义,先求出事件A,B同时发生的概率P(AB)=(C_5^2)/(C_100^2 )=1/495,所以P(B|A)=(P"(" AB")" )/(P"(" A")" )=(1/495)/(5/100)=4/99.6.在某次考试中,要从20道题中随机地抽出6道题,若考生至少答对其中的4道题即可通过;若至少答对其中5道题就获得优秀.已知某考生能答对其中10道题,并且知道他在这次考试中已经通过,求他获得优秀成绩的概率.解:设事件A为“该考生6道题全答对”,事件B为“该考生答对了其中5道题而另一道答错”,事件C为“该考生答对了其中4道题而另2道题答错”,事件D为“该考生在这次考试中通过”,事件E为“该考生在这次考试中获得优秀”,则A,B,C两两互斥,且D=A∪B∪C,E=A∪B,由古典概型的概率公式及加法公式可知P(D)=P(A∪B∪C)=P(A)+P(B)+P(C)=(C_10^6)/(C_20^6 )+(C_10^5 C_10^1)/(C_20^6 )+(C_10^4 C_10^2)/(C_20^6 )=(12" " 180)/(C_20^6 ),P(E|D)=P(A∪B|D)=P(A|D)+P(B|D)=(P"(" A")" )/(P"(" D")" )+(P"(" B")" )/(P"(" D")" )=(210/(C_20^6 ))/((12" " 180)/(C_20^6 ))+((2" " 520)/(C_20^6 ))/((12" " 180)/(C_20^6 ))=13/58,即所求概率为13/58.
